ABSTRACT
This Paper is about the reduction of specific absorption rate (SAR) of wearable rectangular patch antenna for 1.8GHz
and 2.45GHz wireless applications. Antenna is designated on a 3mm X 3mm X 3mm resolution truncated Hugo body
model in Computer simulation technology software. The ramification reveals the specific absorption rate simulated
value that were reduced by 89% compared to previously achieved SAR reduction of 83.5%. A reduction of power
absorption was also noticed as the space of patch antenna increased. The SAR of Patch antennas are reduced from
0.0005 to 0.00041 SAR Avg (mW/g) at frequencies of 1.8GHZ & 2.45GHZ respectively resulting in a significant
improvement in antenna performance. The improvement in directivity & gain has been observed and bandwidth of
about 65% has achieved with Specific absorption rate reduction.
